Main Features
[Type AC Residual Current Protection] Designed to detect sinusoidal AC residual currents and disconnect the circuit when earth leakage is detected.
[Residual Current Sensitivity] Provides 30/100/300mA residual current detection for additional protection against electric shock in residential and similar electrical installations.
[2P and 4P Options] Choose 2P 230V AC for single phase systems or 4P 400V AC for three phase electrical distribution applications.
[Built In Test Button] Integrated TEST button allows regular functional checks to help confirm that the RCD trip mechanism is operating correctly.
[DIN Rail RCCB Design] 63A rated current, 50/60Hz operation and standard DIN rail installation for distribution boards and electrical control panels.

TYPE AC RESIDUAL CURRENT PROTECTION: Detects sinusoidal AC earth leakage currents and is intended for conventional AC circuits with basic resistive or inductive loads where Type AC protection is permitted.
-
2P AND 4P OPTIONS: Available as 2 pole for single phase 1P+N systems and 4 pole for three phase 3P+N systems, with rated current and residual current options for different distribution requirements.
-
RCCB SYSTEM COORDINATION: This set provides residual current protection but not overload or short circuit protection. Install a correctly rated upstream MCB or fuse and confirm that Type AC is permitted for the intended application.
